Effect of phosphor flame retardant on the performance of PPO/HIPS alloy
This paper studies the influence of several different phosphor flame retardants on the performance of PPO/HIPS alloy, and emphatically analyzes the influence of flame retardants on the flame retardant properties of materials.
PPO is the glass transition temperature as high as 220 ℃ noncrystalline resins, molten illiquid, molding difficult, the price is high, the practical application is limited. The processing performance of the polystyrene (Ps), especially the high-impact polystyrene (HIPS), is greatly improved, and the original characteristics of the PPO are basically preserved.
MPPO is the least relative density of general engineering plastics varieties, with a small linear expansion coefficient, good electric properties and characteristics of heat resistant and flame retardant is office equipment, electronics, electrical appliances, auto parts, water supply and drainage good materials of mechanical parts. Unlike other common engineering plastics, PPO and mPPO produce highly concentrated production.
With the improvement of national environmental standards, reduce or don't use contain halogen flame retardants will be the inevitable choice of plastic industry, so the pollution-free, green flame retardant material in the future there will be more broad market prospect.
According to the quality, will weigh good PPO powder, solid flame retardants, HIPS, toughening agent, antioxidant in a high-speed blender mixing 2 ~ 3 minutes, then put the premixed material plasticizing in twin screw extruder, mixing, at the same time through the liquid metering pump the liquid flame retardant added to the barrel, through screw distribution of mixed liquid of flame retardants evenly dispersed in the PPO/HIPS alloy, the extrusion granulation.

Diphenyl Isooctyl Phosphate (S141,362, DPOP) Product Overview
Chemical Classification: Diphenyl Isooctyl Phosphate, Diphenyl 2-Ethylhexyl Phosphate
Diphenyl Isooctyl Phosphate (S141,362, DPOP) Is An Excellent Flame Retardant Plasticizer That Can Be Used In Most Industrial Polymers Including PVC And Its Copolymers, Nitrocellulose, Ethylcellulose, Poly Methyl Cellulose Methyl Ester, Polystyrene And The Like. Diphenyl Isooctyl Phosphate (S141,362, DPOP) Are Generally Used In The Manufacture Of Vinyl Sheets, Coated Fabrics, Inks, Plastics, Rubber And Plastic Foamed Organic Sol, Adhesives, Vinyl And Conveyor Belts. Due To Excellent Solubility, Improve The Performance Of Many Formulations. In Addition, It Can Be The Final Product It Offers The Following Range Of Interesting Properties Such As Flame Retardancy, Low Temperature Flexibility, Abrasion Resistance, Grease Resistance, Excellent Light Stability And Outdoor Weather Resistance And Excellent High Screen Welding Performance. Due To Its Excellent Solubility, Diphenyl Isooctyl Phosphate (S141, 362, DPOP), And Then 3 Phr Of Bismuth Oxide And 10-20 Phr Of Aluminum Hydroxide Were Added.
Diphenyl Isooctyl Phosphate (S141,362, DPOP) Can Be Used As An Excellent Flame Retardant Material For Transparent Films. In Some Fire-Resistant Harsh Colored Films, It Is Recommended To Add Diphenyl Isooctyl Phosphate (S141,362, DPOP) To Significantly Improve The Light Stability And Outdoor Weather Resistance Of The Film.
(S141,362, DPOP) With Diphenyl Phosphate And Tricresyl Phosphate In The Presence Of 10-15% Of Phthalate Plasticizer Such As DOP, Phosphoric Acid Diphenyl Isooctyl Ester (S141, 362, DPOP) Allows The Resulting Plastic To Have A Low Initial Viscosity And A Good Good False Plasticity And Storage Stability. Due To Its Good Pseudoplasticity And Film-Forming Properties It Is Recommended To Add Diphenyl Isooctyl Phosphate (S141,362, DPOP) To PMMA-Based Plastics And Nitrocellulose Coatings And Inks.
Performance test criteria for PPO/HIPS alloy performance by phosphorus flame retardants: the impact strength of the short beam gap: the test is required according to GB/t1043-93; Tensile strength: press GB/t1040-92 to test; Elongation at break: press GB/t1040-92 to test; Bending strength: required test by GB/T 9341-88; Bending modulus: the test is required according to GB/T 9341-88. Combustion performance: tested according to USA UL- 94.
PPO burning charcoal index up to 29, at the same time, molecule contains a large amount of oxygen, suitable for carbon layer formation, in the form of dehydration to keep burning, phosphate ester flame retardant can be very effective, is adopted to realize the process. Phosphorus flame retardant added to the material, the combustion decomposition to produce phosphoric acid or polyphosphoric acid, phosphoric acid through oxidation of PPO, away from the PPO in the form of H2O molecules in elements of H, O, the molecular chain of residual carbon skeleton and not fully burning polymer formed the carbon layer, cut off the internal link between polymer materials and the fire, oxygen and eventually reached the flame retardant.
At present there are red phosphorus and phosphorus flame retardant TPP, BDP, RDP, MPP, etc., on the flame retardant mechanism of it can be used in flame retardant of PPO alloys, but because of the difference of phosphorus content and the molecular structure of the respective difference is bigger, therefore, on the flame retardant efficiency and other performance aspects of material on the influence of the difference is very big, the following is a PPO/HIPS ratio of 60/40, adding different types and number of phosphorus-containing flame retardant effect on the properties of PPO/HIPS alloy.
Several kinds of halogen-free flame retardants in the above experiments, in almost all of the flame retardant added to the material of the PPO/HIPS alloy heat deformation temperature of serious decline, greatly damage the use value of alloy, only in the MPP, cyclic phosphate added to the system to HDT of material damage is very small. Main reason from the TPP, BDP, RDP on the molecular formula of it can be seen that as rich in benzene ring of low melting point organic phosphate, they and the compatibility of PPO is better, so the intramolecular plasticizing effect, improve the exercise capacity of PPO molecular chain under external force, so cause the loss of the alloy HDT.
Therefore, to reduce the influence of flame retardants on HDT only reduces the amount of flame retardant and the new flame retardant. MPP as a kind of inorganic phosphate is equivalent to the effect of filler, so no bad effect to material of HDT, and USES the cyclic phosphate as flame retardants, PPO alloy using the macromolecule flame retardant high molecular weight, molecular contains the characteristics of the annular structure rigidity, reduce the liquid fire retardant agents on the material of the plasticizing effect, improve without halogen flame retardant PPO alloy thermal deformation temperature.
